Hello. Help me, please .Tell me, maybe you encountered a problem. I have chasing m2 pro. The firmware was updated yesterday. Today it stopped making sound when turned on. The remote and cable work. battery is charged 100%. it was just working..and suddenly stopped. water could not get in..Have you seen such a problem? or which board might have stopped working?
The ESC board basically is similar to the ones from a drone. If you turn the ROV on, do you get an image and a connection on the tablet pc or is the ROV just dead?
Hi thank you for disassemble video, do you happen to know what specific pin type (pin size) is used on the connectors? I have a corroded pin on the underside connector
Thanks for a great video. I have a Chasing pro max. I think I had water ingress into the tether connector (where the tether is connected to the ROV). I had video issues and loss of control. Now the ROV will not arm. I get no beeps when I turn the machine on. I think it is a blown ESC or blown flight controller from a short circuit maybe? What do you think? Everything else works. Lights, video work but no motors. Are the ESC's replaceable? Is there a main flight controller that can be replaced?
Hi David, yes the esc should be replaceable… but really hard to perform remote diagnosis. And I don’t know if the esc is available as a spare part. But more importantly is to find the cause of the failure!
@@kopterflug-inspection Thanks! I think the basic cause was salt water getting into the tether/rov connector (the L bend connector) at the back of the ROV. A short circuit here may have caused a failure in the electronics housing. That is my best guess.
@@mawfish1 the tether is basically connected to a modem as the whole system is more or less like ‚ethernet over two wire‘ pretty much the same as vdsl. So I could imagine that there might haben been also some leakage on the inside.. or a faulty / stuck motor might have overloaded the Esc. Hard to diagnose.
@@kopterflug-inspection Thanks for that. Do you know if the flight controller is a pixhawk? Have you seen the main controller the thrusters are wired to?
@@mawfish1 no it’s not a pixhawk, both the m2 and m2 pro have custom pcbs that are stacked by connected with connectors. There is a modem, an led controller, a flightcontroller and an esc board. The camera is a sony imx, I think 1/2.3“ but should have wider FOV and larger sensor
I’m just curious…what do you do/what could be done if sand gets into the motors? Can the motors be taken apart and cleaned? I have the blades off and the sand is actually internally in the motor.
Hi Joshua, if you have used the M2 in Seawater, I am sure that's not sand but corrosion. In my opinion the motors can't be taken apart, but if you remove on propeller screw, you could apply WD40 or marine silicon grease (spray) into the motor. Are you sure that's sand? I never managed to get sand in the motors.
